Are these spider mites?
Hi everyone. I am a first time grower experimenting before I spend money on decent clones or seeds. I started noticing very fine powdery white spots on two of my indoor plants. I got a bit concerned when they looked rather alive under closer inspection with my microscope. A few friends have suggested that they may be spider mites but have not suggested what I should do about them. The plants are about six to eight weeks into flowering.
Any advice would be greatly appriciated.
